Description
The M62366GP is a CMOS semiconductor IC, containing 12 channels of 8-bit D/A converters, with a high-
performance buffer operational amplifier provided in the output of each channel. It is operable with a low supply
voltage between 2.7 to 3.6 V, and is easy to use due to serial data input, and 3-pin (DI, CLK, LD) connection with
microcomputer.
The IC also contains D_O pin terminal, enabling cascade connection. The built-in buffer operational amplifiers are of
full-swing design with a wide operating supply voltage range for input/output voltage. In addition, this IC provides
improved stability against a capacitive load, and therefore is suitable for application to electronic volume (VCA) control,
substitute for adjustment semi-fixed resistor, etc.
Features
• Operable with a low voltage between 2.7 to 3.6 V
• 12-bit serial data input (connected via 3 pins: DI, CLK, LD)
• 12 channels of R-2R and segment type high-performance 8-bit D/A converters
• 12 buffer operational amplifiers with full swing of output voltage between V_CC and GND
• High oscillation stability against the capacitive load of buffer operational amplifiers
Application
Adjustment/control of industrial or home-use electric equipment, such as VTR camera, VTR set, TV, and CRT display.
